I upgraded to 5.1.1 (and iTunes 11) successfully but have had one issue and that is that when streaming from Home Sharing the feed will just stop when the home computer goes to sleep. This happens when streaming music or movies and can be avoided by extending the sleep period.

This did not happen before the update and may be an iTunes rather than ATV issue.

No problem here. My only minor complaint is that the new "Home Movies" which appears in iTunes 11 does not have a corresponding area in the aTV display. So from an aTV perspective, it does no good to move my home movies to it's own category. Only matters for iTunes viewing.

Also, I find the movie cover art to load a lot more slowly than my music cover art. This is probably due to my music cover art being stored on my MBP (where my music is stored) vs my movie cover art being on a networked drive (where my movies are stored). The lag for the movie cover art appearing is relatively short but it is there and it is annoying. Cover art takes so little room, I'm surprised it's not cached on the aTV.

Videos over Home Sharing keep dropping for me. Didn't have this issue at all before updating to 5.1.1 and iTunes 11. Video just stops playing randomly and the Apple TV goes back to the home screen. Going back in, the video will resume from where it left off.

This sounds like the sleep issue. Check your sleep settings in the Energy Saver Preference Pane in Systems Preference. Set it to 2 hours or more and see what happens.

I haven't had a chance to play with iTunes 11 yet, but I'd love it if it had better support for home movies. Is this just another category or genre or something?

I have this problem too. But I've only upgraded iTunes to 11. I haven't upgraded my Apple TV2. (it's jailbroken, so I likely won't upgrade it).

My symptom: Now when I stream a movie or show from my iTunes Library via Home sharing, the show plays, but I will get intermittent pixelation or the image on the screen will freeze for ~5 seconds or longer while the audio continues, OR the program will just drop out, with a "there was an error loading this content" message on the ATV2. I can stop and resume the program, but the same pixelation/freezing issues will occur at the same times as before. This problem did not occur before I updated to iTunes 11, and first occurred immediately after I upgraded, and has been consistent (and annoying) since then.

Workaround: it seems that this problem is unique to Homesharing. If I instead use Airplay in iTunes on my mac to send the show/movie to my Apple TV, I do not experience the symptom. This is fine, but inconvenient since I now have to go sit at my computer to launch a show instead of sitting on the couch.

Worry: I wonder if the Apple TV update is required to quell this symptom. That would be bad because I use the jailbroken features on my ATV2 a lot and so I don't want to upgrade to the latest ATV firmware and lose my jailbreak, just to get back functionality I already had before the iTunes 11 update broke it.

Having the same problem. Home Sharing stops the video multiple times during playback. Very annoying! This started with the recent iTunes update. I thought the new Apple TV update would fix the issue but it does not.

After a few (2 - 15) minutes the movie drops off line and the main menu screen shows up. After that it takes forever to reload the library and selecting a movie immediately drops me back to the main menu screen and it will not play.

I then have to close and re-open iTunes before anything will play, although I must admit I have not tried de-selecting home sharing etc. When I get it working and go back to the movie I was watching and select 'resume' it actually backs up about thirty seconds from where it stopped previously.

I updated my ATV2 & ATV3 yesterday and watched stuff on both of them and didn't have any issues.

Although the [updated] Remote.app on my iPhone crashed many times yesterday and that was aggravating.

That's strange...I hadn't used it for a while, but was having a play with it last night...works perfectly on my iPhone and my iPad....I actually prefer it to the mini remote control, as its too easy to press two buttons at once using it. As far as the update goes, I had I initial issues with the download on my cabled ATV but once I'd sorted that out things are fine...no issues to report and both ATV3's are working perfectly.

5.1.1 proved to be a nightmare for my Apple TV3. It was only a month & a half old.

Once I downgraded back to 5.0.2, everything worked again...for about a day and a half. I spent 2 days perusing forums trying everything, including using ethernet after it initially worked flawlessly using wifi. Finally, when it wouldn't even recognize my apple ID & password (iTunes would with no problem), I'd had enough. I rarely buy extended warranties but after being told these gadgets break down far too often, I did. It was the best $14 investment I've made. The store dude didn't even blink, just told me to go pick out a new one. So far, it's working fine. I hope it lasts, I'd be pretty miffed to find myself with a useless $100 shiny black paper weight.
